PointD

public PointD()

Constructs a PointD at (0, 0).

PointD

public PointD(double x,
      double y)

Constructs a PointD with given coordintes.

Parameters:

x - the x coordinate

y - the y coordinate

PointD

public PointD(android.graphics.PointF pt)

Constructs a PointD from given PointF

Parameters:

pt - the PointF where to take the coordinates

PointD

public PointD(android.graphics.Point pt)

Constructs a PointD from given Point

Parameters:

pt - the Point where to take the coordinates

PointD

public PointD(turtle.GGVector v)

Constructs a PointD from given GGVector

Parameters:

v - the GGVector where to take the coordinates

PointD

public PointD(PointD pt)

Constructs a PointD from given PointD

Parameters:

pt - the PointD where to take the x and y coordinates

Method Detail

set

public void set(double x,
       double y)

Sets the coordinates to given values.

Parameters:

x - the new x coordinate

y - the ney y coordinate

set

public void set(android.graphics.PointF pt)

Parameters:

pt - the PointF from where to copy the coordinates

set

public void set(PointD pt)

Sets the coordinates to coordinates of given PointD.

Parameters:

pt - the PointD from where to copy the coordinates

getX

public double getX()

Gets the x coordinate

Returns:

the x coordinate

getY

public double getY()

Gets the y coordinate

Returns:

the y coordinate

equals

public boolean equals(java.lang.Object obj)

Checks whether the x-y-coordinates of the given PointD are equal to the x-y-coordinates of the current PointD (overrides Object.equals()).

Overrides:

equals in class java.lang.Object

Parameters:

obj - the object whose coordinates are checked

Returns:

true if the given object is of class PointD and has the same (x, y) as the current PointD; otherwise false

clone
